用css给网站增加一个渐变背景

首先我们用css实现增加渐变背景,我们用css定位标签,

增加css代码就可以实现了全局渐变背景了。
body::before {
content: '';
position: fixed;
top: 0;
left: 0;
right: 0;
bottom: 0;
z-index: -520;
pointer-events: none;
}
body::before {
background: linear-gradient( 90deg, rgba(247, 149, 51, .1), rgba(243, 112, 85, .1) 15%, rgba(239, 78, 123, .1) 30%, rgba(161, 102, 171, .1) 44%, rgba(80, 115, 184, .1) 58%, rgba(16, 152, 173, .1) 72%, rgba(7, 179, 155, .1) 86%, rgba(109, 186, 130, .1));
}
